  • Ridged waveguide feed structures for reconfigurable antenna
    Patent number: 10256548
    Abstract: A reconfigurable holographic antenna includes a metamaterial layer and a waveguide with at least one ridge. The metamaterial layer includes an array of tunable slots configurable to form holographic diffraction patterns. A reactance of each tunable slot in the array of tunable slots is individually tunable. The at least one ridge influences coupling between tunable slots in the array of tunable slots. The holographic diffraction patterns formed by the array of tunable slots generate a desired antenna wave in response to a received feed wave.

  • Surface scattering antenna improvements
    Patent number: 10090599
    Abstract: Surface scattering antennas provide adjustable radiation fields by adjustably coupling scattering elements along a wave-propagating structure. In some approaches, the scattering elements are patch elements. In some approaches, the scattering elements are made adjustable by disposing an electrically adjustable material, such as a liquid crystal, in proximity to the scattering elements. Methods and systems provide control and adjustment of surface scattering antennas for various applications.
